METAL-FLANGING MACHINE.

SPECIFICATION forming part of Letters Patent No. 745,665, dated December 1, 1903.

Application tied June 12, 190s.

.To a/ZZ whom t may concern:

Be it known'that I, THEODOR REIS, acitizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and -useful Improvements in Metal-FlangingMachines, of which the following is a specification.

The object of my invention is to provide a combined cutting and anging machine whereby large circular heads used in making large-sized cans, barrels, dto., are cut and flanged in one setting.

Another object of my invention is to provide a power-machine whereby 'the crosshead of the machine may be raised and lowered by means of power and power means to revolve the metal-supporting plate for cutting and flanging. Y p

The machine as shown is adapted for additional use, that of fitting and securing the head upon the body of the cans by appro- .top plan view thereof.

priate mechanism, as shown in my Letters Patent No. 547,183, granted October 11, 1895, or'with other appropriate mechanism.

The features of my invention are more fully set forth in the description of the accompanying drawings, forming a part of this specification, in which- Fgure lis a central section, partly in elevation, of my improved machine. Fig. 2 is a sectional view of one of the flange-forming dies and its supporting means. Fig. 3 is a Fig. 4 is an end elevation of the same. Fig. 5 isa top plan view of the other or lower flange-forming die. Fig. 6 is a vertical section view through onel of the metal pressure-rollers and its support. Fig. 7 is asection on line :r an, Fig. 6. Fig. 8

is a diagrammatic view of the iirst Hangingl operation. Fig. 9 is a diagrammatic view of the second or finishing operation.

A represents the bed of the machine, provided with upright columns A', -on which is adjustably supported the cross-head B. The upright columns are connected at the top by the con neming-beam A2, u on which are suitably supported the power elevating means. B represents the cross-head engaging the columns A,which serve as guides upon which the cross-head slides.

C represents screw-rods having threaded engagement with the outer extremities of the Serial No. 161,201. (No model.)

d d2 represent bevel-gears normally meshing with the bevel-gear d and loosely mounted on the shaft D2, gear d2 being held in place by the collar d3.

d4 represents a clutch (shown in Fig. 1) splined to shaft D2 and adapted to be clutched with the clutch members of either of the gears d d2, thereby enabling a forward or reverse rotating of the shaft D2.

D3 represents a shifting-lever in connection with the clutch d4, adapted to shift the clutch into engagement with either one of the respective clutch members of the gears d cl2.

D4 represents a shaft suitably journaled upon the cross beam A2, being provided at one end with a bevel-gear D keyed thereto, in mesh with a bevel-gear D5, fixed on shaft D2, said shaft D4 being provided with bevelgears 1 and 3 xed thereto, in mesh with bevel-gears 2 and 4, fixed to the screw-rods C. Through this transmission the cross-head, by means of' the engagement of the screwrods G,'is raised and lowered as desired.

' 1I represents a revolving head, upon which is secured the form platen H'. This platen 'H' is of a size equal to the diameter of the can for which the heads are formed. Varying sizes of platens may be employed for corresponding varying sizes of cans.

g2 represents a shaft having bearing in the.

sleeve g3 of the base A and held in position by means of the flange g4. 1

g' represents a bevel-gear keyed to the shaft g2 at its lower end,while the head H is keyed upon the opposite end and adapted to be revolved therewith. G represents a clutch splined to shaft D', adapted to be shifted into engagement with the clutch member of the driving-pulley D to a drive-shaft D'.

G' represents a bevel-gear fixed to shaft D' and in mesh with gear g', through which transmission the head H is given rotation.

The sheet metal to be formed is supported upon thc platen H' and held by means of the following instrumentalities:

H2 represents a swivelng platen-head journaled concentric to platen H' and mounted upon a spindle h,.which is journaled in the sleeve h'. Said spindle is adapted to have Vertical movement in its journal-bearing in order to enable compression to be applied through the head H2 upon the sheet metal supported on the platen H'. Said sleeve h' is mounted in a central bore of the cross-head B. In order to hold the upper platen-head H2 down toits work, I have provided a weighted lever I, provided with a presser-foot I3, and hinged to a bracket I', mounted on the cross-head.

I2 represents a chain for operating the lever I, holding the presser-foot down on the spindle h, and thereby clamping the upper head down upon the platen and lower driven head.

The mechanism for cutting the sheet metal into the circular form is substantially the same as that shown in my former patent in construction and operation, except the parts are differently mounted and combined.

J represents a tool-stock adjustable and connected to the bed in the usual manner for connecting such tool-stocks.

j represents a circular cutter journaled on the tool-stock.

K represents a tool-stock adjustably mounted on the cross-head and carrying a revolving cutter 7c journaled thereon.

The two cutters are driven by their frictional engagement with the sheet metal on the platen, and the metal is cut in circular form by the revolving of the lower head and its contained platen at one revolution, lever I4, clutch G, pulley-wheel D being the actuating means.

The anging mechanism is mounted on the bed-plate and cross-head upon opposite sides of the platen. Itis preferred to cut the head first and then iange it afterward, and -for this purpose the Hanging mechanism is made adjustable by means of levers adapted to raise and lower the Hanging member mounted upon the cross-head. In order to make the obtuse flange without injury by too abrupt' ers may be raised and lowered by means of a crank-arm applied to the shaft Z. These rollers L hold the outer edge of the sheet metal down on the revolving platen, and thereby prevent the metal from buckling toward the clutch under the action of Hanging. N represents the lower Hanging-roll, loosely journaled upon shaft n, as shown in Fig. 5, said shaft being supported upon ears extending from the stock N'. The lower Hanging-roll Nis moved inward toward the machine-center by means of the shifting-lever N2. n represents acoil-spring normallyholding the flanging-roll N away from the platen H'. M represents the upper Hanging-roll, loosely journaled upon the shaftm. This shaftis mounted in an eccentric sleeve fm', which may be turned to adjust the flanging-roll vertically for proper relation with the lower Hangingroll. The shat't and sleeve are supported by a boss formed on the cross-plate M', whichis supported by rods M2 and coil-springs M3, mounted for vertical adjustment upon the cross-plate M4, (see Figs. 2, 3, 4,) said crossplate M4 being adjustably secured to the cross-head B. The vertical adjustment is accomplished by means of eccentrics O', fixed to shaft O. Shaft O is in turn mounted upon the cross-plate M4. As the shaft O is turned in one direction it depresses the cross-plate M', thereby adjusting the upper Hanging-roll M downward to give it the requisite hanging pressure. P represents a lever pivoted at one end to a projection from the cross-plate M' and to the shaft m, operating against spring tension for manipulation of the upper Hanging-roll M. (See Fig. 3.)

The llanging operation is as follows: After the metal has been cut to a circle the flanging-dies are brought to the position shown in Fig. 8. Preferably while the platen H' is being rotated the cutting-tool j is working on one side of the machine, while the i'langingrolls M N are operating upon the trimmed edge of the blank on the other side of the machine. The bearing-rollers L hold the edge of the blank firmly down on the platen H'. In this first step (shown in Fig. 8) the trimmed edge of the blank projects beyond the edge of the platen and lies upon the hub of the lower roll N. The upper roll M is given a lateral adjustment between the edge of the platen and the flange of the lower roll N. It is then brought down vertically, giving to the edge of the blank an obtuse bend. In the next revolution of the platen the rolls are given the position shown in Fig. 9, the straight edge or inner edge ofthe roll M clamping the edge of the blank vertically againstthe edge of the platen, the periphery of the flange of roll M clamping the edge of the blank down upon the hub of the roll N, and the bevelface of the liange-roll M clamping the extreme outer edge of the blank against the bevel-face of the flange of roll N. These heads can obviously be quickly cut and crimped without danger of buckling.

IiO

Preferably at least two steps are employed for the flanging. It will be noted that with the rolls in the position shown in Fig. 9 the metal between the edge of the platen and the inner straight edge of tne flange of roll M is at right angles to the plane of the blank on the plat-en. If such an abrupt turn were made in a single operation-that is, bending from the horizontal plane of the blank to the vertical plane of the flange-it `would be apt to cnt the metal. Therefore to rst give the' obtuse angle of Fig. 8 and lthen bend from this obtuse angle to the right angle of Fig. 9 is obviously the safest operation. It is possible to accomplish this langing in one revolution by immediately bringing the rolls in position shown in Fig. 9, but when done it has a tendency at times to injure the texture of the metal, and it is preferred to do the anging in two step movements.

Various forms of Hanging may be made by simply changing the design of the rolls.

It is obvious that the machine herein shown and described is adapted to be used both as a circular-trimming machine and a flangingmachine. Preferably, as shown and i described, the cutting and trimming and first step of Hanging may be `formed simultaneously.
